Because of economic downturn in the world, most people have become jack of all trades and master of non. learning skills and not getting a mastery of them because they are testing waters on which of them will eventually pay the bills.

It really depends on the person. If you know you're not getting anything out of what you're doing, that means you should stop and focus on something else that can be beneficial.
Of course, if we want to gain something, we should put our effort into things where we know we can truly get a profit.
